Strength training and resistance training
|
Any exercise/activity that requires the
body’s musculature to move (or attempt to move) against an opposing force |
|
Weight training
|
a specific type of strength/resistance training using free weights or some kind of machine
|
|
Modes of Exercise
|
Bodyweight
Machine Free weight Bands |
|
Types of Muscle
|
• Smooth (organs)
• Cardiac (heart) • Skeletal (moves limbs) o Type I (red, endurance) o Type II (white, short fast bursts) |
|
Gains in Strength
|
• Increase cross-sectional area
• Increase neuromuscular coordination |
|
Isometric
|
muscular action where muscle length unchanged under resistance (muscle force equals external resistance)
|
|
Isotonic
|
a muscular action in which a muscle exerts a constant tension
|
|
Types of Isotonic Muscle Action
|
o Concentric – muscle gets shorter under resistance (muscle force is greater than the external resistance)
o Eccentric – muscle gets longer under resistance (muscle force is less than external resistance) Force capabilities 120- 160% greater than in concentric actions |
|
Free weights and machines are __________
|
not isotonic because the muscles exert differing
amounts of force through the ROM based on mechanical advantage of the joints |
|
Dynamic Constant External Resistance
|
a resistance exercise like machines or free weights in which the external resistance does not change
|
|
Isokinetic
|
a muscular action performed at constant angular limb velocity (special equipment needed)
|
|
Repetition
|
one complete movement of an exercise
|
|
Set
|
a group of repetitions performed continuously without stopping or resting ~ Written example: 5 x 12 (5 sets of 12 reps)
|
|
Muscle Actions
|
isometric, isotonic, isokinetic
